Ocean Declaration Commonwealth leaders adopted the 'Apia Commonwealth Ocean Declaration for One Resilient Common Future', which called on all 56 Commonwealth nations to protect the ocean in the face of rising sea levels, pollution and over-exploitation. It called for recognizing maritime boundaries as fixed, even if rising sea levels cause islands to be submerged. According to
Reuters, this would mean resources such as fishing grounds would continue to belong to an island state even if it became submerged and its people relocated. The declaration also called for protecting oceans, restoring degraded marine ecosystems by 2030, finalising the
global plastic pollution treaty, ratifying the high-seas biodiversity treaty, developing coastal climate adaptation plans, and strengthening support for sustainable "
blue economies".
Australia–Britain partnership A 'Climate and Energy Partnership' was agreed between Australia and Britain, intended to focus on accelerating renewable energy development by co-operating on such technology as green hydrogen and offshore wind power generation. Australian Prime Minister
Anthony Albanese stated that the partnership would “ensure we maximise the economic potential of the net zero transition, and build on our long-standing cooperation on international climate action and shared commitment to reach net zero emissions by 2050.” ==Slavery reparations==
